Developing methods to predict electromagnetic instabilities in cardiac dynamics is crucial. However, a comprehensive view of the heart's magnetic activity at a tissue scale is still needed. To address such a challenging problem, we present a theoretical framework to investigate thermoelectric cardiac dynamics from the magnetic field perspective. Our framework demonstrates that periodic stimulations of cardiac cell strands create an external magnetic field, revealing predictable features of nonlinear spatiotemporal cardiac dynamics. Magnetic restitution curves better discriminate instabilities and bifurcations through a thermo-electro-magnetic map analysis. This new approach lays the foundation for innovative, noninvasive diagnostic tools for cardiac arrhythmias.

Abstract

Developing methods to predict electromagnetic instabilities in cardiac dynamics is crucial. However, a comprehensive view of the heart's magnetic activity at a tissue scale is still needed. To address such a challenging problem, we present a theoretical framework to investigate thermoelectric cardiac dynamics from the magnetic field perspective. Our framework demonstrates that periodic stimulations of cardiac cell strands create an external magnetic field, revealing predictable features of nonlinear spatiotemporal cardiac dynamics. Magnetic restitution curves better discriminate instabilities and bifurcations through a thermo-electro-magnetic map analysis. This new approach lays the foundation for innovative, noninvasive diagnostic tools for cardiac arrhythmias.
